LUBRICANT CUP.

Application filed October 17, 1921.

To all whom it may concern Be it known that we, CLARI-1N(E H. JOR- GENSEN and Pn'rrn J. Jononnsnn, citizens of the United States, resldlng at lVaupaca, in the county of Vaupaca and State of W isconsin, have jointly invented certain new adapted to confine a supply of lubricant and gradually deliver the same to a surface of the element requiring lubrication.

One object of the invention is to provide a lubricant cup that can contain an absorbent or wick-like filler and yet be filled promptly, at periods of replenishment, as for instance by applying a so-called oil gun to the cup and forcing a full charge of lubricant thereinto; and to this end an inn portant feature of the invention consists in constructing the cup with a provisional chamber in addition to its wick-containing reservoir so that in addition to the supply of oil that passes directly into the reservoir, an increment of lubricant will remain in the distributing chamber in quantity at least suflicient to respond to the full absorptive capacity of the wick or even in excess thereof if desired; one feature incident to the preferred means for realizing this object of the invention consisting in forming the inner end of the provisional chamber, and the partition between it and the reservoir, by a transverse diaphragm that is perforated to pass the lubricant therethrough;

and another such incident feature consisting in utilizing this diaphragm to support the wick in the wick reservoir.

Another object of the invention is to provide means whereby in the charging of the cup, a quantity of lubricant sufficient to flush the bearings, will pass directly to the bearings, independently of the wick. and without taxing the reservoir supply there for; and to this end another important feature of the invention consists in introducing, between the charging and discharging ports, a direct delivery duct through which lubricant may flow directly to the hearing; one feature incident to the preferred means for realizing this object of the invention consisting in the extension ofthe direct delivery duct from the provisional chamber through the} reservoir to the dischar e port of the Serial No. 508,367.

cup; another such incident feature consist ing in mounting said direct delivery duct in and having it carried by the diaphragm; and still another such incident feature consisting in continuing the direct delivery flushing duct upward into, or, if desired, even through the provisional chamber, so that the provisional chamber will receive its quota of oil at the beginning of the charging operation and the increment which it is to subsequently feed to the wick, will not be drained therefrom by said duct.

Another object of our invention is the provision of a lubricant cup in which the flow of oil therefrom to the bearing is automatically controlled by a tube forming a conduit which extends from the bearing? longitudinally of the discharge conduit of the oil cup and through which air is supplied to the oil cup and controlling the oil fed to the bearing.

In the accompanying drawing, in which the preferred embodiment of the invention is disclosed by way of illustration:

Figure 1 is a vertical axial section of the lubricant cup.

Figure 2 is a side elevation of the same.

Figure 3 is a detail view on an enlarged scale of the diaphragm, the direct delivery duct mounted therein, and the wick supported thereby; and

Figure 4 is a section on the line a -4 of Figure 1.

1 represents the lubricant cup'which may be constructed of any conventional design and dimensions, but which, according to the present invent-ion is equipped with a charging port 2 preferably having a gun-attaching neck 2 a discharge port 3, in the threaded attaching end 4, and a transverse diaphragm 5 having flow-openings 6, and suitably sustained, as for instance, by ledge 7, in position to subdivide the internal space of the cup into a provisional chamber 8, and a reservoir 9. Within the reservoir 9 is an absorbent 10, preferably in the form of strands of wick laced through openings 6 and thereby supported on the diaphragm 5, and trailing thence through the reservoir and into the delivery port 2, beyond which it will preferably protrude a distance suflicient to wipe upon the surface to be lubricated. The wick 10 will largely fill the area of the flow openings 6 that are not closed by the ledge 7, so that splashing of fluid lubricant upward from the reservoir 9 will be resii'ted, but lubricant can, nevertheless, pass from chamber 8 into and around the wick in reservoir 9, under the pressure of the gun. I

The direct deliveryduct is provided, preferably, by inserting a tube 1.1 centrallyin the diaphragm 5 and having it extend downwardly through the reservoir to the (ischarge port so that on each occasion of replenishing the cup, lubricant'will be conveycd directly to the bearing, to which the cup is applied, and thereby flush or prime the latter, independently of the supply through the wick, leaving to the wick the more gradual supply to be effected by capillary action as the lubricant is consumed. Provisional duct 11 will preferably have an upward extension 11 terminating above diaphragm 5 suiliciently to cause the trapping of a considerable body of oil in the provisional chamber, and prevent the same being drained out through the-direct channel, but will not be permitted to obstruct delivery into the provisional chamber. Preferably the action will be to first fill the provisional chamber and such space as may be available in the wick containing reservoir and then permit the direct delivery and flushing effect to result from the overflow.

The provisional chamber 8 lends itself advantageously, in operative principle, to the described organization of parts, in that, upon forcing lubricant, oil for instance, into the chamber 8, the oil may, at first, flow into the duct 11, but flushing or priming of thebearing direct will follow the resistance resulting from filling the reservoir 9, around the wick therein, and largely the spaces among the fibers of the wick, then backing up into and filling the provisional chamber and leaving the'latter an ample increment to supply any deficiency which develops as the process of wick absorption proceeds.

It will also be further understood that the provisional tube 11 performs a further function of permitting-entrance of air into the main reservoir, thus allowing the lubricant contained therein to pass into the reservoir 9 and from there through the wicking to thebearing. As long as there is a quantity of oil maintained around the end of the provisional tube 11 air is prevented from 'enteringthe tube 11 but as soon as this oil is distributed throughout the bearing or is used, air ispermitted to enter the tube 11 and an additional quantity of oil is supplied to-the bearing.

Diaphragm 5 serves the further function of sustaining the closing. spring 12 of a ball valve 13 with which the charging port is preferably equipped, and theextension 11 serves to center said spring. \Ve claim: I
